possible issue on version 12.31 and 12.32

Hi, I've installed the last version from Google Play and downloaded the last version of the World nav database for my home country, Brazil.
the next day I was on a flight and I just couldn't add waypoints to a route from the search page.
I can open the add waypoint page (+WPT) and I can search or browse the database, but when I select the waypoint that I want to add to my route, I get back to the Edit route page and I see a "unable to open database" alert.
if I use the Map edit button everything works fine.
my databases are on my SD card and I have a Samsung Galaxy Tab 7 Plus, rooted. it has worked perfectly until now.
does anybody else have this same problem, or is it just me?
maybe it's a bug?
I'm not being able to export from my World database as I was before, but I'm getting a message that it's no longer possible ("Export from the World database is not allowed").
thanks,
Xavier
P.S.: version 12.32 shows the same issue.
